Application filed February 18, 1889- Serial No. 300.249. (No model.)

T0 107007711 i m y H 7 being attached to the upperends of levers (Z (I, Be it known that I, EDWIN E.

Said lever is mounted to swing upon the filed by me. The cans are allowed to drop rod c, and has a trundle-roll F, which enters one at a time from the chute by a feeding a cam-groove G in a disk II on the shaft f. 85 mechanism, hereinafter described, upon a The rotation of said disk oscillates the lever movable support or arm I), which is mounted C and causes it to reciprocate the slidesAA', to swing on a fixed rod or support 6, attached and thereby sinniltaneously move one slide to the frame of the machine, and is operated into and the other out of the chute a. Said bya cam, hereinafter described, so as to stand slides are separated by a space about equal 0 40 under the chute aand between the can-body to the diameter of one can-body, and when clamps o c in position to arrest and support the lower slide A is moved out from the a can-body dropping from the chute until chute the can-body thereon is released and the said clamps clasp the can-body, and then allowed to drop, the slide A being at the move away, so as to be out of the way of the same time moved inwardly to arrest the next 95 5 devices that apply the heads to the can-body. can-body above. After the discharge of the Said arm or support I) has stops or projeccan-body the slides A A are moved in the tions 1), which retain the can-body in place opposite direction, the slide A being thus and prevent it from moving endwise. The moved into the chute to arrest the lower can clamps c c are semicircular and are arranged body, which is allowed to fall upon it by the I00 at opposite sides of the point where the canoutward movement of the slide A.

body is supported by the arm I), said clamps j j represent holders or carriers located at opposite ends of the clamps c 0, each holder having connected to it by bolts or pivots 7; two levers m m, having jaws m formed on their outer ends. Said jaws are semicircular and project over the inner ends of the holders j. A slot 0 is formed in the holder j behind the jaws m, to permit the insertion of the flanged can-head behind the jaws. Means are provided for opening and closing the jaws, as hereinafter described, and when the jaws are closed their edgescoincide with the inner surface of the flange of the can-head, so that the can-head cannot pass through the .circular opening between the jaws m. 111 each holder j is a cavity 1), communicating with the slot 0, said cavity receiving the can head dropped through said slot. In the cavity p is a plunger or follower (1, which is normally forced forward by a spring 'v, the purpose of which will be hereinafter explained. Said plunger (1 is attached to the rod 7', which passes through the holder j, and is adapted to slide longitudinally in said holder, and in a guide .9, which is formed 011 a swinging frame 5, and is fitted to move vertically in a slot t in an arm a, formed on a slide '10, which slide is fitted to move between guides y y on the supporting-frame. 011 said slide are arms 2, to which are pivoted at 3 arms 4, formed on the swinging frame .5. The holder j is fitted in a socket in the frame 8, and said frame, with the slide to, is moved longitudinally to carry the holder j and its jaws m toward and from the can-body, held by the clamps c, by a cam 41 on the shaft f, said cam receiving a trundle-roll 5, supported by an arm 20 on said slide. In addition to its longitudinal movement, the frame 8 has an oscillating movement on the center or pivot 3, said movement being imparted by means of a vertical connecting-rod 6 and a cam-groove 7 in adisk 8, attached to the shaft f, said rod 6 being fitted to slide in guides 9, attached to the supporting-frame. The rod 6 is pivoted to a collar 6, in which the rod 1' is free to slide lengthwise. The rotation of the cam 8 causes the rod (5 to alternately raise and lower the outer end of the rod 0. It will be seen, therefore, that when the outer end of the rod r is lowered the jaw-carrier will be inclined, so that the can-head therein will be inclined from a vertical position, its upper portion being thrown outwardly farther from the end of the can-body to which it is to be applied than its lower portion, while the upward movement of the rod 0' will restore the can-head to a vertical position. The described movements of the rod 0' are so timed that when the slide w is moved outwardly to carry the jaws away from the can-body the outer end of the rod 1' is depressed to give the described inclination to the can-head, and when the slide w is moved in the opposite direction to carry the jaws toward the can-body the outward end of the rod 4 will remain depressed until the lower portion of the flange of the can-head comes to a bearing on the corresponding point of the can-body, after which the outer end of the rod 2' is raised, thus bringing the jaws and can-head. to a vertical position and completing the application of the flanged head to the end of the can-body. The head is thus brought gradually toabearin g on the end of the body, the movement being similar to that employed in applying a flanged head or cover to a cylindrical box or can by hand, so that the head is more easily and certainly applied than it would be if held parallel with the end of the can-head when first presented thereto. The office of the plunger q is to support the can-head with a yielding pressure against the jaws m whilethe head is being applied to the can-body, the spring 4; normally pressing the plunger forward and permitting it to yield slightly, so that in case there is any unusual resistance to the application of the can-head to the body, caused by imperfections in the flange of the can-head or otherwise, the plunger (1 will yield, and thus prevent breakage of or injury to the parts through which the head-applying pressure is exerted and imparted.

The plunger is thrown back from the jaws to permit the insertion of a can-head while the jaws are receding by means of a lever12, which is pivoted at 13 to cars on the slide in and bears at its upper end against a collar 14 on the rod r. The lower end of said lever projects below the slide 20 and is provided with an adjustable screw or stud, which, when the slide to is moving backwardly, strikes the fixed supporting-frame, the lever 12 being thereby turned on its fulcrum and caused to give the rod 1 and plunger q an independent backward movement. While the plunger is thus held back a can-head is dropped into the cavity 1) through the slot 0, and when the slide win moving forward to carry the jaws toward the can-body removes the lever 12 from contact with the supporting-frame the spring 2; forces the rod r and plunger q forward and causes the plunger to hold the canhead flange against the closed jaws m. Said jaws remain closed during the application of the can-head to the can-body, their inner edges being flush with the inner surface of the can-head flange, so that they closely embrace the can-body when moved forward. The jaws are opened after the can-head is applied to the body by means of a plate 15, fitted to rotate on the carrier 3', and provided with cam-grooves 16 16, Fig. 2, which receive the rear ends of the jaw-levers m. Said plate 15 has a slot 17, which receives a stud 18 on a lever 19, which is pivoted at 20 to the supporting-frame, and has at its lower end a trundle-roll 21, which enters a cam-groove 22 in a disk 23 on the shaft f. The rotation of the disk 23 causes the lever 19 to oscillate, and in turn to oscillate the plate 15, the camgrooves 16 16 being thus caused to move the levers m m, and thereby open or close the jaws m m, as the case may be. The jaws are opened just before the carrier j is moved outwardly away from the can-body, and are closed immediately after they have passed away from the can-head flange, so that they are in position to hold the flange of the n ext can-head in the manner already described.

The general operation of the machine is as follows, it being understood that in the organized machine there are two of the can-headapplying mechanisms above described, both operating simultaneously, so that both ends or heads are applied to the can-body at once. A can-body is first dropped 011 the support ing-arm Z) from the chute while the clamps c c and the holders j j are at the outward extremes of their movement. The clamps c c are then moved inwardly and caused to grasp the can-body, after which the supporting-arm b is moved to one side and the holders j j advance in their inclined positions and present the lower portions of the can-heads to the can-body held by the clamps c c, and are then made horizontal by the upwardmovement of the rod 4', thereby completing the application of the can-heads, the jaws being then opened and the holders j moved back, as already described. After the jaws have receded from the can the clamps c c are opened and the can drops therefrom into the discharge-chute 21.

Parts of the machine hereinbefore described are shown and claimed in three other applications filed by me concurrently herewith viz, the can-bodysupplying or letting-off de vices and the clamps that hold the can-bodies while they are being headed in application Serial No. 300,250; the head-holding jaws in application Serial No. 300,248, and the mechanism for applying the can-heads to the canbodies in application Serial No. 300,247.
